frikeando Posted March 17, 2017 Share Posted March 17, 2017 Hi all, I have a 5440 (Intel graphic card and 768p screen). I successfully install Sierra, everything working but wifi and audio. Regardless the change I want to make, audio or wifi drivers, on next boot the screen dims to black when apple logo. If I boot with -v, it keeps happening. It's not that the screen suddently goes black, but slowly in about 1 second. In safe mode everything goes well, I get to the OS. If I install official wifi drivers (TP-Link TL-WN725N), it happens. If I try to fix the ALC292 audio, it happens. Any guess what happens? Thanks Link to comment Share on other sites More sharing options...
Administrators Hervé Posted March 17, 2017 Administrators Share Posted March 17, 2017 What exactly do you do when you "try to fix the ALC292 audio" ? ALC292 requires: 1) installation of dummy ALC292 kext in /L/E 2) patching of AppleHDA (2 x patches) in /S/L/E 3) cache rebuilding Link to comment Share on other sites More sharing options...
frikeando Posted March 23, 2017 Author Share Posted March 23, 2017 I tried with VodooHDA, but sound stops working after some minutes. Where do I find ALC292 instructions and files? What can I do regarding the screen going black on startup? Thanks. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted March 23, 2017 Moderators Share Posted March 23, 2017 Where did you get your Bootpack from? What BIOS version are you running? Could be the DSDT you're using is from another version of Bios, that would cause strange this like this. Boot to Clover menu, hit F4, then continue to OS X. Compress and attach Clover folder here.

frikeando Posted April 10, 2017 Author Share Posted April 10, 2017 After lots of testing, I am always stocked in the same thing. I create a bootable USB with the EFI folder I attach, install Sierra. Everything works OOB (I replaced the wifi card) but sound, which I patch with the file I also attach. Great, everything is OK. But whether I install Clover... Anything I do, the screen dims slowly to black if I try to boot it from Clover. If I boot from the USB and select HDD, everything works. Re: ALC292, check my E6440 Sierra guide for dummy ALC kext & AppleHDA patching instructions. For the sound, I just use kext utility/kext wizard with the kext I attach, nothing else required and Int works. AppleHDA.kext.zip EFI.zip Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted April 10, 2017 Moderators Share Posted April 10, 2017 You're manually patching AppleHDA and using Clover Hot-patches, stick with one or the other, not both. If you're using the Clover hotpatch, you'll need to restore the vanilla AppleHDA and install a dummyHDA and disable patch AppleHDA #4, not needed for Sierra.

frikeando Posted April 10, 2017 Author Share Posted April 10, 2017 This is not a problem. The sound works! The thing is that when I install clover and then I copy the CLOVER folder into the EFI folder inside EFI partition, the laptop does not boot. If I boot from that USB with the EFI folder I attached, it boots. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted April 11, 2017 Moderators Share Posted April 11, 2017 so the screen goes dark and stay dark? can you hit Fn+Insert a few times to see if it comes back on? is it sleeping with the power button flashing? Link to comment Share on other sites More sharing options...
frikeando Posted April 11, 2017 Author Share Posted April 11, 2017 It stays black, yes. If I push Fn+Insert, nothing happens. It is not sleeping, as the power button is bright and the HDD led indicates the laptop is doing things. Thanks a lot. Link to comment Share on other sites More sharing options...
